I came across a web page where a guy said he bored his bike out and made it a 1300. How much would that cost? I'm just curious...I'm still learning how to ride; my '97 Bird is my first ride.

he is going to get a hayabusa???
is this what you're asking?
c'mon peps lets busa

If I come cross his page again, I'll copy the link.

I don't know about 1300, but there's a kit out there for a 1200cc "big bore" conversion. Here's one. I don't think there's enough cylinder wall to get to 1300cc with just boring. You'd prob have to get a new crank/rods and stroke the thing too.

That sounds nuts regardless. If you did get a 1200 conversion kit what's the difference, 1137/ 1200, wait "1195?"
Hell, I've only gotten up to 95mph and I almost pissed my pants cause I was going into a curve and it was the first time on the highway! LOL! I like the fact that the speedo registers 205mph, but I'll never see anything close to it...I think

The difference will be about 5 percent increased torque (about 2% or 5 km/h extra top speed). Unless you are not planning to bore the block and replace the pistons anyway, it is not worth it. You will get the same increase in torque on the rear wheel on all gears if you change the front sprocket from 17t to 16t. The top speed may go down a bit but basically it will reduce some top speed that is never used by most people. If you need substantially more power and torque, you may consider a turbo upgrade. On the other hand, how many averages above 200 km/h on roads and needs a lot more power? Of course it would be fun but the real application for a turbo is probably on a drag strip. I would think different if there already was a turbo on my bike Much is nice but more is better if one chose the right situations to use the power.

No need to push it. Sounds like a sane and safe choice to keep the speed reasonable. The XX is fast enough stock. Unless you are planning on going drag racing no need to punch it out. If you feel the need for speed all you have to do is twist the throttle. Plenty on tap.

i'm always looking for more horse's ! no granted when i bought my bb i thought i would never seek anymore ponies but sh!t happens

Sounds like there are some horse power junkies in here!

Definitely not trying to push the Bird yet I bought it from my cousin who had ridden my uncles '83 interceptor all through high school. He said he could just never twist the throttle enough on it. I talked to him last night, he said he did change the sprocket from a 17 to 16(When I bought it, he just said it was new). It's got a 4-2-1 Vance and Hines exhaust. My cousin said he had up to 160mph...I prolly won't see that either. Anyways, I need to put it back together so I can get rollin again.

I have been through the 1123 big bore kits on my CB1100F bikes and decided that they are for the drag strip guys who want to tear down their engines on a regular basis.
Nothing good comes from a big bore kit unless you are a drag strip maniac.
Enough power can be added to the bike with a proper exhaust system and remapping of the ignition for a fuel injected bike or a bank of proper mechanical slide carbs for a carbed bike.
My Bird is fast but, she is too quiet with the stock exhaust and that is not thrilling enough for me.
So I bought a titanium Akropovic 4-2-1 exhaust system for her and will buy a Power Commander as soon as I sell my black air cooled dinosaur.
The CB1123R bike pictured below is why I will not do anymore big bore kits, she is much faster than a stock CB1100F but, she also weighs at least 100 pounds less than a stock CB1100F. I have had to replace the rings twice because after market rings suck and are for the friggin birds.
Honda makes the best rings I have ever run across, so leave your bike alone and forget about big bore kits unless you like breaking down your motorcycle on a regular basis.

Thanks for the advice. I really don't plan on doing anything except getting this things running and reliable first and foremost. I took the tank off and realized this is really an 11 yr old bike. I don't THINK there's anything seriously wrong with it other than needing some hoses replaced along with the plugs(if I ever get them out!) and an oil change.

I'm not mechanically inclined by any means with bikes, so I'mma keep flippin through this manual and get it done and appreciate it a heck of a lot more!

Smart man.
Make sure that when you are working on your bike that you pay very close attention to what you are doing and have fun.

You cant get 1300 out of a BB without stroking it. There just isn't enough space between the cylinders. After having seen a bored out block even 1200 is pushing it in my opinion.
Now turbos are another story.......

I'll admit, when it comes to BIKES, I have an issue when someone has an 12 or 1300. Maybe it's a man thing, maybe I'll get over it....one day.

Actually, it's those damn busas, I'm tired of hearing about them. One of the main reason I got my Bird is because I STILL haven't seen another one out!
